Abstract

Système de charge de batterie (100), chargeur (110) et batterie intelligente (160) améliorant la sécurité lors de la recharge d'une cellule (180) dans la batterie intelligente (160) par une alimentation électrique (130) du chargeur. La batterie intelligente (160) peut communiquer avec le chargeur (110). Si une défaillance de communication se produit, le chargeur (110) déconnecte l'alimentation électrique (130) de la batterie intelligente (160). La batterie intelligente (160) et le chargeur (110) partagent la même clé de chiffrement symétrique pour chiffrer et déchiffrer des données de message, permettant à une partie de déterminer si l'autre partie est authentique. Lorsque la batterie intelligente (160) trouve que le chargeur (110) n'est pas authentique, ou vice versa, l'alimentation électrique (130) et la cellule (180) sont déconnectées. Lorsque la batterie intelligente (160) trouve qu'une condition de non-charge se produit en raison d'une anomalie dans la cellule (180), la batterie intelligente (160) demande au chargeur (110) d'arrêter la charge, et déconnecte également la cellule (180) du chargeur (110), même si le chargeur (110) ne parvient pas à arrêter la charge de la batterie intelligente (160).
